Figures 3.14 & 3.15. • Must have an approved and Listed cap • Must not be located where it will become plugged by snow or other material • Must terminate at least 3 feet (91 cm) above the roof and at least 2 feet (61 cm) above any portion of the roof within 10 feet (305 cm). • Must be located away from trees or other structures NOTICE: • Chimney performance may vary. • Trees, buildings, roof lines and wind conditions affect performance. • Chimney height may need adjustment if smoking or overdraft occurs. E. Locating Your Appliance & Chimney Location of the appliance and chimney will affect performance. As shown in Figure 3.13 the chimney should: • Install through the warm space enclosed by the building envelope. This helps to produce more draft, especially during lighting and die down of the fire. • Penetrate the highest part of the roof. This minimizes the affects of wind turbulence and down drafts. NOTICE: Locating the appliance in a basement or in a location of considerable air movement can cause intermittent smoke spillage from appliance. Do not locate appliance near • Frequently open doors • Central heat outlets or returns • Consider the appliance location in order to avoid floor and ceiling attic joists and rafters. • Locate termination cap away from trees, adjacent structures, uneven roof lines and other obstructions. Your local dealer is the expert in your geographic area and can usually make suggestions or discover solutions that will easily correct your flue problem.

Venting & Draft Management A stove is part of a system, which includes the chimney, the operator, the fuel, and the home. The other parts of the system will affect how well the stove works. When there is a good match between all the parts, the system works well. Wood stove or insert operation depends on natural (unforced) draft. Natural draft occurs when the exhaust is hotter (and therefore lighter) than the outdoor air at the top of the chimney. The bigger the temperature difference, the stronger the draft. As the hot gases rise through the chimney they provide suction or ‘draw’ that pulls air into the stove for combustion. A slow, lazy fire with the stove’s air inlets fully open indicates a weak draft. A brisk fire, supported only by air entering the stove through the normal inlets, indicates a good draft. The stove’s air inlets are passive; they regulate how much air can enter the stove, but they don’t move air into it. Depending on the features of your installation - steel or masonry chimney, inside or outside the house, matched to the stove’s outlet or oversized - your system may warm up quickly, or it may take a while to warm up and operate well. With an ‘airtight’ stove, one which restricts the amount of air getting into the firebox, the chimney must keep the stove’s exhaust warm all the way to the outdoors in order for the stove to work well. Some chimneys do this better than others. Here’s a list of features and their effects. Draft, Chimney Height & Performance This appliance was tested for emissions on a 15 foot chimney, using a combination of single wall chimney connector & insulated class A pipe. The unit requires a draft between .03 and .065 in of H2O. The draft measurement should be taken with an active fire, the damper closed and the air control at the maximum setting. If the draft is below .03 in of H2O, the unit may have issues operating with the damper closed and may back-puff into the room on lower burn settings. If the draft of the chimney system is too low, additional vertical height should be added to the system or the number of elbows/tees in the system should be reduced. The venting system should have no more than a total of 180° of turns (2 x 90° elbows, 4 x 45° elbows or any combination). Two 45° elbows create less draft reduction than a single 90° and can be substituted for installations with low draft. Tall chimney systems, particularly internal Class A systems may generate draft which is well above 0.65 in of H2O. In that case, the unit may experience short burn times, difficulty controlling the burn rate of the stove and the potential for overfiring. In the past, stack dampers could be recommended in these installations, but manufacturers are no longer permitted to specify these on EPA Certified models. The chimney system should be carefully reviewed and draft tested (if possible) prior to installation of this unit. Masonry Chimney Masonry is a traditional material for chimneys, but it can perform poorly when it serves an ‘airtight’ stove. Masonry is a very effective ‘heat sink’ - it absorbs a lot of heat. It can cool the chimney gases enough to diminish draft. The bigger the chimney, the longer it takes to warm up. It’s often very difficult to warm up an outdoor masonry chimney, especially an oversized one, and keep it warm enough to maintain an adequate draft. Steel Chimney Most factory-made steel chimneys have a layer of insulation around the inner flue. This insulation keeps the chimney warm. The insulation is less dense than masonry, so a steel chimney warms up more quickly than a masonry chimney. Steel doesn’t have the good looks of masonry, but it performs much better. Indoor/Outdoor Location Because the chimney must keep the smoke warm, it’s best to locate it inside the house. This uses the house as insulation for the flue and allows some heat release into the home. An indoor chimney won’t lose its heat to the outdoors, so it takes less heat from the stove to heat it up and keep it warm. Single Venting Each ‘airtight’ stove requires its own flue. If an airtight stove is vented to a flue that also serves an open fireplace, or a leakier stove, it’s easier for the chimney draft to pull air in through those channels and performance of the stove suffers. Imagine a vacuum cleaner with a hole in the hose to understand the effect here. In some cases the other appliance can even cause a negative draft through the stove, and result in a dangerous draft reversal. Flue Sizing The inside size of a chimney for an ‘airtight’ stove should match the size of the stove’s flue outlet. When a chimney serves an airtight stove, more is not better; in fact, it can be a disadvantage. Hot gases lose heat faster as they travel slower through a chimney; if we vent a stove with a six-inch flue collar (28 square inch area) into a 10 x 10" flue, the gases slow to one third their original speed. This allows the gases to cool more rapids, which weakens draft strength. If an oversized flue is also outside the house, the heat it absorbs gets transferred to the outdoor air and the flue usually stays cool. It is common for a masonry flue, especially one serving a fireplace, to be oversized for the stove. It can take quite a while to warm up such a flue, and the results can be disappointing. The best solution to an oversized flue is an insulated steel chimney liner, the same diameter as the stove or inserts flue outlet; the liner keeps the exhaust warm, and the result is a stronger draft. An non-insulated liner is a second choice - the liner keeps the exhaust restricted to its original size, but the hot gases still must warm up the air around the liner. This makes the warm-up process take longer. Vermont Castings • Intrepid FlexBurn® Installation Manual_R23 • 2018 - ___ • 06/23 153-90-30007345i B.

Smoke and CO Detectors & Safety Tips Smoke and CO Detectors The use of smoke and carbon monoxide (CO) detectors throughout the home is strongly advised, even if not required by building codes or insurance regulations. It is a good idea to install a smoke detector in the living areas and each bedroom. Follow the smoke/CO detector manufactures placement and installation instructions and maintain regularly. You may not, however, wish to install a detector in the immediate vicinity of the stove. Depending on the sensitivity of the unit, the alarm can be set off while you are tending the fire or emptying the ashes. If you install a detector in the same room, locate it as far away from the stove as possible. Safety Tips Conveniently locate a “Class A” fire extinguisher to contend with small fires. Be sure the fire extinguisher works and is clearly visible. All occupants of the house should know where it is, and how it operates. Have heavy stove gloves available near the stove. Have special safety accessories (e.g., Child Guard Screen) available for use if small children will be in the home. In the event of a stove pipe or chimney fire…. • Evacuate the house immediately • Notify the fire department • If the fire isn’t too threatening, closing down the stove tight, (damper, primary air, all doors) will help to smother the fire. • Inspect your stove, vent pipe and chimney for any damage caused by the fire and correct any damage before using your stove again. Fire Risk • Do not leave the fire unattended when the door is unlatched • Operate only with front doors and ash pan door closed. • Unstable firewood could fall out of the firebox creating a fire hazard to your home.
